This number called me 3 times yesterday and left no message. I mistakenly answered it today and it was a staticy message which I couldn't understand. As a matter of fact it almost sounded like someone was holding the phone up to a radio broadcast. Now in my no ring category, but I expect that my number is now reset in their autodialer and they will call me mercilessly since that is what they do best to further their criminal endeavors.
I have been getting regular calls from 303-425-1075 which is in my no ring also, so maybe it is them spoofing their number to con me into answering.
